Types and Uses of Paper

Study Notes

Definition

Paper is a thin material used for writing, printing, packaging, and various other purposes.

Composition

Made primarily from cellulose fibers derived from trees, grasses, and other plant materials.
Can also include additives for strength, brightness, and other properties.

Types of Paper

Writing Paper
- Used for notebooks, letters, and documents.
- Typically smooth and of medium thickness.
Printing Paper
- Designed for printing quality; includes varieties like copy paper and photo paper.
- Graded by weight and finish (e.g., gloss, matte).
Cardstock
- Thicker than regular paper; used for business cards, invitations, and crafts.
Specialty Paper
- Includes recycled paper, handmade paper, and paper for specific uses like art or legal documents.
Packaging Paper
- Used for wrapping and protecting items; includes kraft paper and cardboard.

Manufacturing Process

Pulping
- Raw materials are broken down into cellulose fibers.
- Chemical or mechanical methods can be used.
Sheet Formation
- Fiber slurry is spread onto a conveyor and pressed to remove water.
Drying
- The wet sheet is dried to create a continuous roll or large sheets.
Finishing
- The paper is cut, rolled, and often coated or treated.

Characteristics

Weight (measured in grams per square meter - GSM).
Brightness (reflectivity of light).
Texture (smooth, rough, etc.).
Opacity (degree of transparency).

Environmental Considerations

Sustainable sourcing from responsibly managed forests.
Recycling options; paper can be recycled several times.
Impact of production on deforestation and water usage.

Uses

Office supplies (notebooks, sticky notes)
Artistic applications (drawing, painting)
Packaging and shipping materials
Hygiene products (toilet paper, tissues)

Historical Context

Originated in ancient China (2nd century BCE).
Evolved from scrolls to sheets, leading to the printing revolution.
Innovations such as the printing press boosted demand and usage.
